Description

Technical Field

[0001] This invention relates to the field of ore loading machines, and more specifically to a device for preventing spillage on a loading machine. Background Technology

[0002] In the invention patent application entitled "A Mobile Loader with a Double Telescopic Boom Structure" (publication number: CN103569691A, publication date: 20140212), the invention includes a head car and a tail car. The tail car is connected to the head car via a traction rod. The head car is equipped with a double telescopic boom and a double-stage three-channel bifurcated funnel. The double telescopic boom consists of a main loading boom and a secondary loading boom installed side by side. Both the main loading boom and the secondary loading boom are telescopic booms. The double-stage three-channel bifurcated funnel includes an upper bifurcated funnel and a lower bifurcated funnel. Both the upper and lower bifurcated funnels have three channels: a main loading channel, a secondary loading channel, and a waste material recycling channel. The main loading channel is connected to the main loading boom, and the secondary loading channel is connected to the secondary loading boom. This invention enables the continuous and quantitative loading of bulk cargo (such as coal and ore) into open wagons, while also meeting the usage requirements of electrified railway stations. This makes the use of mobile loading machines in electrified railway stations possible and is applicable to electrified railways with overhead contact lines.

[0003] In ore mining, the mined ore is first stored in a sheltered mine, and then loaded onto trucks by a loading machine and transported to various parts of the country for further processing. Existing loading machines mainly use screw feeders to transport the ore to the loading point. However, during the loading process, after the ore is conveyed to the screw feeder, the position of the screw feeder needs to be adjusted or a loader needs to be used to transport the ore to the position of the screw feeder, which is a rather cumbersome operation. Summary of the Invention

[0004] The purpose of this invention is to provide a device for preventing material spillage on a loading machine, so as to overcome the above-mentioned shortcomings in the prior art.

The device also includes a material gathering mechanism rotatably connected to the feed end of the frame for conveying ore to the position of the screw feeder; and a transmission assembly disposed on the frame and connected to both the material gathering mechanism and the screw feeder. When the screw feeder rotates, the transmission assembly drives the material gathering assembly to swing at the feed end of the frame, thereby gathering the ore at the position of the screw feeder, facilitating the loading of the ore by the truck loader.

[0007] Preferably, the material gathering mechanism includes two shovels rotatably connected to the feed end of the frame, and each shovel is slidably connected to a pusher plate.

After each of the shovels rotates to a preset position, the second execution unit drives each of the pusher plates to slide on the shovels corresponding to them, thereby conveying the ore to the position of the screw feeder.

[0010] Preferably, the first execution unit includes a cam coaxially fixedly connected to both ends of the screw feeder and two transmission rods slidably connected to the frame, each of the transmission rods moving on the motion trajectory of the cam corresponding to it.

[0011] Preferably, the first execution unit further includes a rotating shaft fixedly connected to each of the shovel plates, a transmission groove is formed around each of the rotating shafts, and a transmission block adapted to the transmission groove is provided on each transmission rod.

[0012] Preferably, the second execution unit includes an arc gear fixedly connected to each of the shovel plates and a driven gear corresponding to each of the arc gears. Each arc gear meshes with the corresponding driven gear after the shovel plate rotates a preset angle.

[0013] Preferably, each of the driven gears is rotatably connected to the frame, and each of the driven gears is coaxially fixedly connected to a wire roller, on which a steel wire rope is wound, and the other end of each steel wire rope is fixedly connected to the push plate corresponding to it.

[0016] In the above technical solution, the present invention provides a loading machine anti-spillage device, which drives the transmission component to move during the rotation of the screw feeder, so that the transmission component drives the material gathering mechanism to move, thereby causing the material gathering mechanism to gather the ore at the position of the screw feeder, thereby reducing the number of times the screw feeder position needs to be adjusted.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The present invention provides a loading machine anti-spillage device, which, by setting up a material gathering mechanism and a transmission component, causes the transmission component to drive the material gathering component to swing at the feed end of the frame when the screw feeder rotates, gathering the ore at the position of the screw feeder, which facilitates the loading machine to load the ore and prevents spillage. At the same time, it can reduce the number of times the frame needs to be adjusted or the number of times the loader pushes the material. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] Reference Figure 1-8 As shown, the present invention provides a loading machine anti-spillage device, including a frame 1 and a conveying mechanism 1.1 rotatably connected to the frame 1. A screw feeder 1.2 is rotatably connected to the feed end of the frame 1. The device also includes a material gathering mechanism, which is rotatably connected to the feed end of the frame 1 and is used to transport the ore to the position of the screw feeder 1.2.

[0032] Transmission assembly: It is mounted on the frame 1 and is connected to the material gathering mechanism and the screw feeder 1.2 respectively;

[0033] When the spiral feeder 1.2 rotates, the transmission component drives the material gathering component to swing at the feed end of the frame 1, thereby gathering the ore at the position of the spiral feeder 1.2, which facilitates the loading machine to load the ore.

[0034] Specifically, the arrangement of the frame 1 and conveying mechanism 1.1 in this invention is merely a schematic diagram; the actual ore loading machine used in production shall prevail. The frame 1 is equipped with movable wheels (not shown in the figure). A screw feeder 1.2 is rotatably connected to the frame 1 at its feed end. A conveying mechanism 1.1 is rotatably connected to the discharge end of the screw feeder 1.2. The conveying mechanism 1.1 includes a connecting frame and two pulleys rotatably connected to the connecting frame. A conveyor belt is fitted onto the pulleys, and one of the pulleys receives the first... The motor 1.11 is driven and fixedly connected to the connecting frame. In order to adjust the unloading height of the conveying mechanism 1.1, one end of the connecting frame is hinged to the frame 1, and the other end of the connecting frame is a free end. Two telescopic rods 1.12 are hinged between the connecting frame and the frame 1, thereby realizing the adjustment of the unloading end height of the conveying mechanism 1.1. In this embodiment, the telescopic rods 1.12 and the first motor 1.11 can be controlled by PLC or by manually closing or opening a switch.

[0035] A material gathering component is rotatably connected to one end of the screw feeder 1.2. The material gathering component swings at both ends of the screw feeder 1.2, causing the ore to accumulate at the position of the screw feeder 1.2. Therefore, after the ore is loaded by the loader for a period of time, the ore at the position of the screw feeder 1.2 becomes difficult to transport. At this time, it is necessary to use a loader to push the ore to the position of the screw feeder 1.2 or to adjust the position of the frame 1 to move the screw feeder 1.2 to a position with more ore. The material gathering mechanism is fixedly and rotatably connected to the position of the screw feeder 1.2 on the frame 1, which reduces the number of times the loader pushes the material or the number of times the position of the frame 1 needs to be adjusted.

[0036] The transmission assembly is mounted on the frame 1. One end of the transmission assembly is connected to the screw feeder 1.2, and the other end is connected to the material gathering mechanism. That is, during the feeding process of the screw feeder 1.2, the material gathering mechanism can also be driven to swing on both sides of the frame 1, so that the ore can be gathered at the position of the screw feeder 1.2. In this embodiment, the transmission assembly rotates two sets of mutually perpendicular circular motions. In the prior art, bevel gears or other mechanical structures that can convert two sets of mutually perpendicular circular motions into each other are applicable to this embodiment.

[0037] During use, after the unloading of the conveying mechanism 1.1 is raised to a suitable height by the telescopic rod 1.12, the first motor 1.11 is started, and the conveying mechanism 1.1 starts to work. At this time, the transmission component drives the screw feeder 1.2 to rotate, and the screw feeder 1.2 drives the material gathering mechanism to swing on both sides of the frame 1 during the rotation process, so that the ore is gathered at the position of the screw feeder 1.2, which makes it convenient for the loading machine to load the ore and reduces the number of times the frame 1 is adjusted or the number of times the loader pushes the material.

[0038] The present invention provides a loading machine anti-spillage device, in which the screw feeder 1.2 drives the transmission component to move during rotation, which in turn drives the material gathering mechanism to move, thereby causing the material gathering mechanism to gather the ore at the position of the screw feeder 1.2, thus reducing the number of times the position of the screw feeder 1.2 needs to be adjusted.

[0039] Reference Figure 1 , 3 As shown in Figure 5, in another embodiment of the present invention, the material gathering mechanism includes two shovels 1.3 rotatably connected to the feeding end of the frame 1, and a pusher plate 1.4 is slidably connected to each shovel 1.3.

[0040] The transmission assembly includes a first drive assembly and a second drive assembly. The first drive assembly is used to drive the screw feeder 1.2 to rotate, and the second drive assembly is used to drive the material gathering mechanism to rotate.

[0041] Specifically, a shovel plate 1.3 is rotatably connected to both ends of the screw feeder 1.2 on the frame 1. The shovel plates 1.3 are located on both sides of the screw feeder 1.2. A pusher plate 1.4 is slidably connected to each shovel plate 1.3 in the transverse direction. Each shovel plate 1.3 has a groove, and a slider adapted to the groove is fixedly connected to each shovel plate 1.3, thereby allowing the pusher plate 1.4 to slide in the transverse direction of each shovel plate 1.3, such as... Figure 3 As shown, the first drive component is the second motor 1.8, whose output shaft is coaxially and fixedly connected to the screw feeder 1.2, and the second motor 1.8 is fixedly mounted on the frame 1.

[0042] By sliding a pusher plate 1.4 on each shovel 1.3, after the shovel 1.3 rotates to a preset position, the pusher plate 1.4 slides on each shovel 1.3 corresponding to it, thereby conveying the ore to the position of the screw feeder 1.2.

[0043] Reference Figure 3-5As shown, in another embodiment of the present invention, the second drive assembly includes a first execution unit and a second execution unit. The first execution unit is used to drive each shovel 1.3 to swing. After each shovel 1.3 rotates to a preset position, the second execution unit drives each pusher 1.4 to slide on the shovel 1.3 corresponding to it, thereby realizing the conveying of ore to the position of the screw feeder 1.2.

[0044] The first execution unit includes a cam 1.7 coaxially fixedly connected to both ends of the screw feeder 1.2 and two transmission rods 1.6 slidably connected to the frame 1. Each transmission rod 1.6 moves on the motion trajectory of the cam 1.7 corresponding to it.

[0045] The first execution unit also includes a rotating shaft fixedly connected to each shovel 1.3, with a transmission groove 1.31 circumferentially formed on each rotating shaft, and a transmission block 1.61 adapted to the transmission groove 1.31 on each transmission rod 1.6.

[0046] The second execution unit includes an arc gear 1.30 fixedly connected to each shovel 1.3 and a driven gear 1.50 corresponding to each arc gear. Each arc gear 1.30 meshes with its corresponding driven gear 1.50 after the shovel 1.3 rotates at a preset angle.

[0047] Each driven gear 1.50 is rotatably connected to the frame 1, and a wire roller 1.5 is coaxially fixedly connected to each driven gear 1.50. A steel wire rope 1.51 is wound on the wire roller 1.5, and the other end of each steel wire rope 1.51 is fixedly connected to the corresponding push plate 1.4.

[0048] Each roller 1.5 is fixedly connected to a spiral spring 1.52, and the end of the spiral spring 1.52 is fixedly connected to the end of the corresponding wire rope 1.51.

[0049] Specifically, a cam 1.7 is fixedly connected to each end of the screw feeder 1.2. One of the cams 1.7 is coaxially fixedly connected to the output shaft of the second motor 1.8. The second motor 1.8 is fixedly mounted on the frame 1. A transmission rod 1.6 is slidably connected in the vertical direction at the position corresponding to each cam 1.7 on the frame 1. The transmission rod 1.6 slides on the movement track of the cam 1.7. A transmission groove 1.31 is opened around the circumference of the rotating shaft of each shovel 1.3, and each transmission rod 1.6 corresponds to a transmission groove 1. A transmission block 1.61 is fixedly connected at position 31. Each transmission block 1.61 is located in its corresponding transmission groove 1.31. Then, the screw feeder 1.2 drives the cam 1.7 to rotate during rotation, so that the cam 1.7 drives the corresponding transmission rod 1.6 to move in the vertical direction of the frame 1. In turn, the transmission rod 1.6 drives the corresponding shovel 1.3 to rotate. In this embodiment, the preset angle of rotation of the shovel 1.3 can be determined according to the on-site installation and manufacturing requirements.

[0050] An arc-shaped gear is coaxially fixed to the shovel plate 1.3. A driven gear 1.50 meshes with one side of each arc-shaped gear. Each driven gear 1.50 is rotatably connected to the frame 1. The arc-shaped gear 1.30 can only mesh with the driven gear 1.50 after each arc-shaped gear 1.30 has rotated to a preset angle. (Refer to...) Figure 2 , 4 As shown in Figure 6, a linear roller 1.5 is coaxially fixedly connected to each driven gear 1.50, and a spiral spring 1.52 is fixedly connected to the linear roller 1.5. The other end of the spiral spring 1.52 is fixedly connected to the wire rope 1.51. The wire rope 1.51 is wound around the linear roller 1.5, and the other end of each wire rope 1.51 is fixedly connected to the pusher plate 1.4 corresponding to it.

[0051] During operation, after the conveying mechanism 1.1 is raised to a suitable height by the telescopic rod 1.12, the first motor 1.11 is started, causing the conveying mechanism 1.1 to begin working. At this time, the transmission assembly drives the screw feeder 1.2 to rotate, which in turn drives each cam 1.7 to move. Each cam 1.7 drives the corresponding transmission rod 1.6 to move upward, which in turn causes the transmission block 1.61 on the transmission rod 1.6 to move within its corresponding transmission groove 1.31. This causes each shovel 1.3 to rotate. When each shovel 1.3 rotates to a preset angle, the arc gear 1.30 on each shovel 1.3 rotates until its corresponding driven gear 1.50 rotates. This causes the driven gear 1.50 to drive the wire roller 1.5, which is coaxially fixed to it, to rotate. This causes the wire roller 1.5 to wind the steel wire during rotation, which in turn causes the pusher plate 1.4 on each shovel 1.3 to slide until each shovel 1.3... Figure 1 State transition to Figure 3 The ore is gathered at the position of the screw feeder 1.2. When the cam 1.7 drives the transmission rod 1.6 to move downward, the shovels 1.3 are reset. This is considered a material collection process.

[0052] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
